How to Determine if You Need a Warehouse Management System

For instance, line-item allocation: Is an item on an order allocated when the order is entered, picked, packed or shipped? When it’s allocated, is it a “hard” or a “soft” allocation? What about back-ordered items? How do you deal with cancellations?

Among the various order management systems, there’s no universal standard by which line-item allocations on an order are processed. So expecting a WMS to automatically match the way your system currently handles this is unrealistic.
